Can you ovulate on same day as LH surge?

The LH surge indicates ovulation will occur at some point within the next twelve to forty-eight hours (on average). The window is large because it is different for everyone. Some people ovulate the same day as the LH surge and some ovulate two days after the surge.

What is a good LH ratio?

Normally this ratio is about 1:1 – meaning the FSH and LH levels in the blood are similar. FSH and LH are often both in the range of about 4-8 in young fertile women. In women with polycystic ovaries the LH to FSH ratio is often higher – for example 2:1, or even 3:1.

Can you miss LH surge testing twice a day?

Sometimes, the peak time of luteinizing hormone is short and lasts only a couple of hours. To make sure you don’t miss the surge of the hormone, it may be helpful to take the test twice a day. If the peak time is long (more than 24 hours), one test is enough to indicate an increased level of the hormone.

What is Peak LH number?

Most of the time, blood concentration of LH is between 5 – 20 mIU/mL. Roughly 24 – 36 hours before ovulation, LH levels begin to surge to a peak of 25 – 40 mIU/ml.

How long after LH surge do you ovulate?

Ovulation is spontaneously triggered about 36-40 hours after blood levels of a hormone called luteinizing hormone (LH) rise. This is called the LH surge. Once released from the ovary, the egg is picked up by and travels down the fallopian tube where it can meet sperm to become fertilized.
